IMPROVEMENT 1N GALvemc nautisme# Theehqdule referred to ii; these Letters Patent and o( the llme.

To all when: 4 it may concern l `Be it known that L'JAMEs R. MePHEnsoN, of the city of Beloit, of Rock county, in the State of Wisconsin, have invented vcertain new and useful Improvements in Galvanic Batteries, herein-below lfully vdescribed; and I .do hereby declare the following description, and laccompanying: drawings, are sutiicientto enable-any personrsigilieinthe art 'ci' science Vto which it most nearly appertains, to make and use 4my said invention or improvements ywithout furtherinvention or experiment. l

The nature of my invention and improvements consists in the construction and arrangement of the several pai'ts and ingredients constituting an improved galva'nic battery, fullilling substantially about the follow ing conditions .hereinatter setforth and.deseribed, reference being had to the accom pan'yin'g drawings, and 'to'.,the letters of reference marked thereon, similar.

letters of reference indicating corresponding parts; in

- which drawings- Figure 1 is`a.perspective .view of .iny improved hat tery complete in all its parts, and

Figure 2 is a centralvertical section of the same. Letter A represents a jar or poe-made of iron, or

.other suitable metal, oi' any suitable size, which 1 use `for the outside, or negative of the battery,

I thentake an-earthen-or other porous jar, or pot,

O, -of suitable corresponding size, so as 'to Iset inside of l the jar A, leaving. a convenientand suitable'- space, B, between them, according to the size ot' the battery or iin'eness ofthe iron oi' other metal chipsfto 'be-used for iil'ling the space` B between the said jars', (about. half an inchl heilig a medium) I then put some iron tion of either muriatic orsulphuric acid, or a strong solution o f salaminonlac. I then fill the porous jar O,

entirely free.

to about the level lwith the iron chips inthe space B, with black oxide of manganese, marked D, and' nitric acid. I then introduce a cod conduct-or, marked E, (such as coke or piatinum, .weil down .into the inangnncse, and then attach wires', e and b, the same asin ordinary batteries@ l lhe faucet ais-for drawing spent acid from th space B.

The jar C should be considerably taller-"than the iron jar A, for the reason that -the hydrogen that goes to the nitric aeidiliberates nitrousaciii, taking from' the" manganese', and forms nitric :ic-id.

Thenitric acid -is only weakened by dilution, andl not like other strong batteries, where the' introns acidpasses. olf in fumes, which not onlydhite but destroys.

The'fum'es also, being poisouous,vh'avc a deleterious 'influence on the health -of telegraph -opcratorea very serious objection, from which luy-improved battery is The special advantages of this battery aresnbatan-v tially these: l

It is much cheaper, costing only about one-tenth as much as batteries now in use less danger from breaking; fewer changes of acids; has greater volumeof power;` .moi-eintensity; isperfeotIyooUStnnt, and has `no poisonous fnmes,'all which nre very important -eliaracteristies in a galvanic battery.

What I claim as my invention and improvements,

Statesis.

The iron jar A; filled with metal chips .saturated janddesire to secure by Letters Patent ci' the United .with a. .weak 'solution of muriatic or sulphuiic acid, orV

strong `solution o f salam'moniac, in combination with the-inner porous jar C, filled with black oxide of manganese' 'and` nitric acid, and the. conductor E, allarranged tocperate ns hereindescribed and sho\vn.- r JAMES MoPHERSON Witnesses B. DURHAM,l
